Production of Existing System. Understand that we need to replace 4 units. How many unit can we shut down at a time do to the work. That changes our work procedure. In order for us to work without interruption, we need to know capacity and ability of each current unit. Especially the flow load.

Section 01 11 00 Summary of Work, suggests a viable construction sequence, and which treament units may be taken off line and shut down at any given time. Shut down will be one unit by one unit. Needs to be clarified by Waste Water Treatment Plant Manager ( Officially)

5 General

Japanese Waste Water Treatment Plant Law. Japanese Waste Water Treatment System Law. We believe that this will not match the Japanese law once we upgrade the system as described. Should we not to follow the Japanese Law? ①There is no Primary Conditioning Tank ②There is no Third Chemical Sedimentation Process * We need the third process if we need to do the nitrogen removal.

The proposed treatment system will meet JEGS permit requirements.

Microscreens are designed to replace the primary clarifier. Nitrogen removal is accomplished with the use of a pre‐denitrification single sludge nitrification/denitrification system, incorporating Anoxic Zones and an internal recyle system, reducing the reliance on chemicals and eliminating the need for separate nitrification/denitrification stages.

#29, D12P SEAL FAIL is to be "read by PLC only." Additionally to question #23 (Question No. 47) regarding Seal Fail itself, please clarify what kind of data shall the PLC read?

#29, D12P SEAL FAIL is to be "read by PLC only." The "29" is the terminal number on the VFD. The "P" is a typographical error.

"Seal Fail" is a description of the signal, i.e., this input will become true when the Seal Fail Relay changes state, indicating a seal failure in the pump (see answer to Query 47). The "Read by PLC Only" indicates that the PLC reads this VFD input via Ethernet/IP as if it were an input to a PLC I/O module, but does not use it in any control; it just generates a "Seal Fail Alarm" for the pump.

The data for the Seal Fail itself is binary, either it is true or it is false.
